54 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 66 
took part. During the first cruise observations were made at 30 
stations, that is, 8,336 to 8,305 inclusive. These stations extended 
from the lower bay to the mouth of the Patapsco River, while 
during the second cruise 35 stations were examined, Nos. 8,366 to 
8,390 inclusive, which approximately covered the same parts of the 
bay examined during the first trip. The efforts of the members of 
the Museum staff were directed to the securing of bottom samples 
and bottom life, the hydrographic work being done by the repre- 
sentatives of the Bureau of Fisheries. 
Fic. 69.—Looking out through Gregerie Channel, Danish West Indies, where 
much dredging was done. 
The results of these two cruises indicate a remarkable scarcity 
of animal life, the washing of an entire dredge haul frequently 
yielding only a handful of shells, worms, and small crustaceans. The 
bottom material consisted chiefly of mud in a semi-fluid condition, 
which appears to be discouraging to animal life. A few notable 
exceptions were encountered in what one might term garden spots 
in which a decided concentration of living organisms was encountered. 
No shore collecting was done.
